Abstract

A microporous structure with controlled thickness of the porous layer and pore sizes has been prepared on the surface of VT1 titanium alloy by laser surface alloying of TiC powders and subsequent selective etching. It has been shown that the use of relatively coarse titanium-carbide powder particles, 80–100 μm, and the increase in the laser-beam speed to 20 mm/s allow us to form the uniform nanoporous substructure on the internal surfaces of pores.
